India Tightens Rules for Spam Call Identification Apps

India’s TRAI regulator is introducing new obligations for apps that collect spam call reports and expanding oversight of automated A2P calls.

TRAI spam rules are changing how call identification and management apps will handle user reports in India. On September 18, 2026, India’s telecommunications regulator published an amendment to the Telecom Commercial Communications Customer Preference Regulations requiring affected apps to submit spam reports to the DND registry managed by access providers.

The new wording applies to apps that allow users to mark an incoming call as spam or an unsolicited call. Apps are to send reports to operators in a format specified by TRAI. The goal is to connect crowdsourced data from caller identification services with operators’ mechanisms for combating unsolicited commercial communications.

What the TRAI spam rules introduce

The amendment, titled Telecom Commercial Communications Customer Preference (Third Amendment) Regulations, 2026, also covers automated A2P calls—communication from an application to a user—in addition to reports from spam apps.

TRAI classifies automatic dialing, robocalls, and calls with recorded or artificial voices as A2P calls. For these forms of calling, it introduces notification obligations toward operators. The regulator is thus expanding the framework against unsolicited commercial communications to voice systems that may not operate like a conventional call between two people.

Importantly, the rules are not generally intended to take effect on the day they are published. The amendment provides for delayed implementation, so it is not accurate to claim that apps already had to begin transferring data to operators on September 18.

Impact on apps and operators

The rules affect products whose value lies in user-created databases of flagged unknown and suspicious numbers. Under the amendment, operators will have access to reports through an established DND registry mechanism, which may give them additional information when addressing unsolicited commercial calls.

However, it has not been independently confirmed what exact scope of data will be transferred or which specific types of apps the rules will cover. It also remains an open question whether the obligations will apply to system calling apps on Android and iOS, or primarily to standalone third-party apps.

Truecaller called the one-way transfer of user reports to operators anticompetitive. This is the company’s position, however, not a finding by a regulator or court. TRAI confirmed the adoption of the amendment in its notice, but the available confirmed information does not specify the detailed technical model for data exchange or the final scope of all services involved.

What happens next

For app operators and users, the effective date of the specific obligation and TRAI’s implementation guidelines will be important. They are expected to clarify the technical requirements for submitting reports, including the data format and the scope of affected apps.

The responses from Truecaller and other caller identification service operators should also be monitored. Equally important will be how operators use the new reports when blocking spammers and taking action against entities that distribute unsolicited commercial calls.
